Meta Intern (SDE Intern / PE Intern) for 2026 spring + summer hiring runs the OA on CodeSignal. The current format remains "4 problems + 90 minutes", but PE Intern has migrated to a single "Cloud Storage 4-phase" problem. Below: problem-line breakdown per 1point3acres last 60 days + VO assistance roadmap.
Meta Intern OA Snapshot
| Dimension | Detail |
|---|---|
| Platform | CodeSignal |
| Duration | 90 minutes |
| Questions | 4 (SDE) / 1 in 4 phases (PE) |
| Difficulty | 1 Easy + 2 Medium + 1 Hard |
| Grading | Auto + hidden stress tests |
SDE Intern Problem Lines
Type 1: Array + Binary Search
def shortest_subarray_with_sum_at_least(arr, T):
from collections import deque
pre = [0]
for x in arr:
pre.append(pre[-1] + x)
dq = deque()
best = len(arr) + 1
for i, p in enumerate(pre):
while dq and p - pre[dq[0]] >= T:
best = min(best, i - dq.popleft())
while dq and pre[dq[-1]] >= p:
dq.pop()
dq.append(i)
return best if best <= len(arr) else -1
Type 2: String Transformation — LC 76 / 567 / 438 family
Type 3: Graph / Tree — LC 207 / 210 / 1162
Type 4: Hard Closer — union-find / segment tree / bitmask DP
PE Intern Problem Line: Cloud Storage 4-Phase
Phase 1: Basic R/W
upload(filename, size), get(filename), copy(src, dst).
Phase 2: User Isolation
user_upload(user, filename, size), user_get(user, filename).
Phase 3: Backup
backup(user) snapshots state; restore(user, ts) rolls back.
Phase 4: TTL + Quota with LRU Eviction
from collections import defaultdict
class CloudStorage:
def __init__(self):
self.files = defaultdict(dict)
self.quotas = {}
def set_quota(self, user, q):
self.quotas[user] = q
def upload(self, user, fname, size, ts):
used = sum(s for s, _ in self.files[user].values())
q = self.quotas.get(user, float('inf'))
if used + size > q:
order = sorted(self.files[user].items(), key=lambda kv: kv[1][1])
need = used + size - q
for fn, (s, _) in order:
if need <= 0: break
del self.files[user][fn]
need -= s
self.files[user][fname] = (size, ts)
def get(self, user, fname):
return self.files[user].get(fname, None)
High-Frequency Cheat Sheet
| Problem Type | Frequency | Core Pattern |
|---|---|---|
| Array + binary search | ★★★★★ | Prefix sum + monotonic deque |
| String sliding window | ★★★★ | Two pointers + Counter |
| Graph / topo / SCC | ★★★★ | DFS + indegree |
| 4-phase Cloud Storage | ★★★★★ | dict + LRU + snapshot |
| Interval DP / bitmask | ★★★ | Classic templates |

From Pacing Jitters to Passing Meta Intern OA
We were glad to help this cohort pass Meta Intern OA. Many candidates told us they never paced LC practice in 4 × 90-min CodeSignal format — they froze on Q3 and Q4 (Hard) got no attention.
If you're prepping Meta, Instagram, WhatsApp, or Reality Labs Intern OA / VO and feel pacing + 4-phase progressive design is shaky, contact oavoservice. We tailor OA / VO assistance to your gaps.
FAQ
Same OA bank for Intern vs New Grad?
Same backbone; New Grad ups difficulty by one tier (Easy → Medium, Medium → Hard).
Difference between 3/4 AC and 4/4 AC?
3/4 → phone screen; 4/4 → onsite direct.
Must PE Intern do Cloud Storage?
Yes. PE since 2025 standardized on Cloud Storage 4-phase. SDE Intern stays at 4 problems.
Result timeline?
Usually 7–14 days. Full AC may bring a phone screen invite within 3 days.
